No rule is inviolate
Setting books are tricky because I want to support setting books, but I wouldn't buy them if I didn't know the world. In my experience, people want to play Dragonlance not because I said it's cool, but probably because they read the Legend of the Twins and Chronicles trilogies. I have no interest in Eberron because, without having read novels, I don't feel I could make it come alive and breathe (even having played D&D Online, set in Eberron).
